American Airlines has now canceled more than 1,000 flights as it inspects wires in its 300 MD-80 aircraft, the Wall Street Journal reports. The Federal Aviation Administration raised concerns about recent inspections of the wiring, the same issue that grounded more than 400 flights last month. The process, which began yesterday, could stretch past tomorrow and affect half of American's schedule.

An FAA inspector checked several planes Monday and determined some of the work performed last month did not satisfy standards, said an airline spokesman. The required work concerned “very detailed and technical compliance,” he said. The FAA has cracked down on inspections since coming under fire last month for allowing Southwest Airlines to fly planes that had missed safety checks.
